水下航行体分片式艉水平舵操纵性水动力试验

Model test study for maneuverability hydrodynamics of submarine's stern horizontal rudders in different subsection

对水下航行体分片式艉水平舵单片舵叶及其组合的水动力特性进行了风洞试验研究,并对其操纵能力进行了比较、分析。研究结果表明:对试验舵型而言,整体操舵具有最高的舵效,可用于在低速航行时实现对航行体的探控;当航行体在水下高速航行时,可采取单舵片操纵方式,而当航速较低时,可采取组合操舵方式,以保证航行体的水下操纵安全性。

Wind tunnel model test for hydrodynamic characteristics of submarine^s stern horizontal rudders in different subsection was carried out, and their control capabilities were compared and ana- lyzed. The study result shows that integrative operation has the most high efficiency to the test rud- der, that can be used for controlling submarine with low speed. When the submarine is navigating with high speed or middle speed under water, the single subsection operate mode or combinational ope- rate mode or combinational operate mode should be used to ensure the submarine＇s control safety.
